A year ago today a massive earthquake struck Christchurch, New Zealand, leaving 185 dead and the lives of thousands in shambles. The country's second-largest city was horrifically damaged, and to this day aftershocks and unstable buildings have caused large sections of the city to be rendered completely uninhabitable and unsafe. It is a major tragedy, and one which has sadly been too quickly forgotten by the international community.

But out of this darkness comes a light, as at least one publisher is taking action to support those affected by the earthquake. Polar Bear Farm founder Layton Duncan has penned a heartfelt letter on the company blog stating that all Polar Bear Farm apps are going on sale for today only, with 100 percent of the proceeds devoted to earthquake relief. The money will be funneled into a charitable trust with the sole purpose of restoring and rebuilding downtown Christchurch so that the city's inhabitants can have their city back.

For those unfamiliar with Polar Bear Farms, they make a variety of neat utilitarian apps like Showtime, Face Match, Convert, and many more. For a full list of the company's apps just pop them up in iTunes and have a look.

If you're looking to pick up a few new apps this week and also want to do a little social good then this is your chance. Also, please spread the word to friends and loved ones so we can help the people of New Zealand and show them that even a year later they're still on our minds. I mean, the apps are already on sale AND all the money is going to charity, what more reason can you possibly need to contribute?
